To all whom it may concern; Be it known that I, HARRY'S. HART, a citizen ofthe United States, residing at Chicago, in the county of Cookv and State of Illinois, have invented certain neW and useful Improvements in Dump Cars, of which the following is a specification.

This invention relates to a newand' improved dump car construction, and more particularly to a hopper car design particularly adaptedfor usein reconstructing ex isting hopper cars.

As is well known, hopper cars generally used for carryingcoal are commonly .bllllt with sloping end portionsfsloping-downwardlyfrom a point near the upper portion ofthe end of the car to apoint within the trucks, the-floor of the intermediate" portion ofthe car being comprised of hoppers, either longitudinally or transversely arranged as'thecase'may be. 4 ,1

This construction obviously does not take full advantage of the maximum capacity as if it were possible to use the entire space I at enclosed by the sides and ends of the car for load carrying. As meansfor, taking advantage of the entire load carrying cap-acitygof such cars, I have. devised various improvements in such cars, an: example being shown in my prior Patent No. 1,30%969,

granted May 27th,l9 19, which avoidthe loss of space in constructing new "cars;

It is highly desirable that the large number of cars now in use built upon the old uneconomical design should be reconstructed so as to increase the carrying capacity without increasing the other over all dimensions.

It is an object of the present invention to provide a new and improved car design adapted to secure the maximum possible carrying capacity.

It is a further object to provide such a design which is especially adapted for use in reconstructing existing hopper cars.

It is an additional object to provide a reconstruction design which involves the minimum amount of change in existing cars, combined with securing the maximum possible carrying capacity.

Other and further objects will appear as the description proceeds.

In carrying out my invention, I provide a car having vertical sides and ends, the floor portion at the ends comprisingas shown in the present embodiment of my inventio1i-downwardly and outwardly sloping" sections, extending inwardly from the ends of the car towardthe center of the car. These sloping floor sections, however, instead .of extending approximately over the trucks for their full length, as shown in my prior patents,an exampleot which is above ,referredflto, extend to the bolsters only, the remainder of the floor comprising hopper portions which may be of well knoi'vntypes. In illustrating the .iinven tion, I have selected a well known type of par having transverse hoppers between the trucks illustrating my improvement as applied to sucha car. It will be understood,

however, that my invention isequallyapplic-able to hopper cars of other types;

p The sloping hopper floors of such existing hopper cars are commonly ,supportedabove the body bolsters by cross beams extending from the bolsters to the car floor. Broadly,

my invention consists in a car with which the sloping floor stops at thepoint of support byfthese cross, beams. Between this point and the end of the car a floor is provided sloping downwardly toward the, sides of the car. Doors upon "the side of the car are provided for permitting the discharge or material carried-in these end portions. This construction is particularly adapted iorreconstruction purposes, since it is only cross beam and other supporting elements of the sloping floor need not be modified in any way. I

I have illustrated a preferred embodiment of my invention in the accompanying drawings, in which.

Figure 1 is a plan view of one half of a hopper car according to my design;

Figure 2 is' a longitudinal section of Figure 1; and

Figure 3 is a transverse section of the car, the right hand half of the section being taken on line A-A of Figure 2 and the left hand half being taken on line BB of Figure 2.

As shown in the drawings, the car comprises the sides 5, ends 6, center A-portion 7, transverse hopper doors 8 and sloping hopper fioor 9. The transverse doors 8 are operated by suitable mechanism 10. The body bolsters 11 are located at either end above the trucks and extending above these necessary to cut off the existingslopingfioor beyond the connection to the cross beam end to add the newend floors and doors. The

bolsters; are the cross beams; 12, the I per edges of Whichare secured at I3'to opper floor 9.

Between the end of the sloping hopperfloor 13 and the end of the car 6 a floor 14. is provided having downwardly sloping portions 15, these portions 15 bei adapted to discharge through doors 16,:ii iich doors m Ope d b t usual In reconstructing existing cars to eonfoi'm V to; the. present design; thefloor fi is eilt atthe. point 13 in an approximately straight line transversely of the ear the. addi tional fioorportions 15 wavere in I The doors 16, are added together t 3 operatingfmechanisim A's hasheedstated; noaehange. in. the body bolster, or remainder of the floor 9,ijsrqnired; permits change of existing cars at a'tivel'y' small expense.
